Double emails from the list
Anyone know why I get 2 copies of every email sent to this list? Is there something I can do to fix it? Thanks Gareth

User authentication
Here's a question that I havn't seen on the list. I have Cyrus IMAP 2.0.16 installed, and running great for us here. All of the users use Pine from local machines, and would like to not have to type their password to get their mail from the server. Also, I want to implement one-time passwords for users travelling abroad, and since the connection would be unencrypted I don't want them to type the password to read mail. Is there a way to carry some sort of authentication from the local machines to the server? Many users use OpenSSH authentication agents (and if that's the best way to go, I have no problem enforcing it), so there's one possibility. Currently authentication is done with passwd, since I couldn't get PAM and NIS to play well with each other, so adding "+::/bin/false" to /etc/passwd got it working fine. Though we'll hopefully be moving to LDAP soon for other reasons anyway. I would imagine the best solutions would be some way for the server to know that the remote user is authenticated already, and not require a password. Pine wants to do this by using rsh to the mail server, and running /etc/rimapd, but since user logins are disabled on the server I disabled rsh in Pine. Could ssh be used for this? What about Kerberos (which I'd have to learn about before implementing, but there's other users who have requested a few Kerberized services anyway)? Any help would be appreciated.

Re: preventing connect from different ip's if cyrus.conf contains specific binds
yes Ive waited for several minutes, the thing is that another pop3d is
spawned immediately as "ps" shows.
for example in this situation:
22082 p1 I 0:00.07 pop3d: pop3d: localhost.alchemistry.net[127.0.0.1]
(pop3d) |original
22084 p1 I 0:00.03 pop3d |second one
they are both sleeping..
iif I kill 22082, than prompt appears immediately in the telnet
I know for sure that master is listening this is output of sockstat:
cyrusmaster 22064 12 tcp4 127.0.0.1:110 *:*
cyrusmaster 22064 15 tcp4 192.168.0.3:110 *:*
it just that pop3d doesnt work properly I guess. ?
a quick gdb look said that its running function fcntl ?

You can't specify multiple interfaces in one line, but you can have multiple lines, as long as you use a unique service name for each. ie: imap-lo cmd="imapd" listen="localhost:imap" imap-eth0 cmd="imapd" listen="[192.168.1.1]:imap" imap-eth1 cmd="imapd" listen="[192.168.2.1]:imap" -- Kenneth Murchison Oceana Matrix Ltd.

Re: preventing connect from different ip's if cyrus.conf contains specific binds
Works for me. Are you waiting a few seconds for the service to be
spawned by master (since prefork=0)? If master wasn't listening on the
given interface, you'd get something like this:
telnet: connect to address 192.168.0.3: Connection refused

/etc/cyrus.conf : listen=multiple ip's
I want my imap and imaps-services listening on multiple (but no all) ip's on my server. Can I specify more than one host in the listen-directive or can I specify multiple lines with the same service and different hosts ? thnx, peter

same thing:
